Last, and actually least, is the "Kamaka" hard case that often comes with Kamaka ukuleles. It is almost as light as the Kamoa and almost as functional as the Ameritage but not as good as either. The exterior is covered with a pleather like black substance that I found peels and scratches easily. So unless you want your case to be covered in stickers, it is going to look worse for the wear.
It has three latches, which function fine, but lack the style of the Kamoa ones or the heartiness of the Ameritage ones. The handle is plastic, and not nearly as comfortable to hold as the ones found on the other cases. It is the middle size of the three, with a length of 31", a width at the widest point of 11", and a height of 5". With the uke inside, it weights 4.5 pounds, and it also lacks a strap option. As I did on the Ameritage, I drilled the d rings with the strap attached so I could carry it on trips.
It does have a compartment, albeit a skinny one. The compartment is as long as the Ameritage one, at 5" long, but it is only 2" high and 2" across. You can fit a tuner and string winder in there, or a humidifier, but that is about it. When I used this case, I used a pouch similar to that I made for the Kamoa, so I could carry extra strings and accessories.
My Kamaka ukulele fit well within the case and its plush, faux fur lining (as I suppose it should since it is the "Kamaka" case). It did, however, have the most excess room at the headstock of the three options (2"), but the velcro strap across the fretboard was a nice way to secure the uke into its case. (Oops not in use in this photo).
These cases can be had for about $75 but to be honest, I would skip them. I have never owned a Kala case, but lots of people swear by those cases and they just seem to hold up better than these Kamaka ones do. I had one metal staple in this case that kept cutting into me, and the pleather was peeling in a lot of spots. I ended up getting rid of mine when I bought the Kamoa case. I told them to donate it to the next person who couldn't afford a case for their new ukulele -- someone ended up buying it from them for $30 used, which isn't a bad price but it isn't worth much more than that.
In conclusion, I think it is a toss up between the Ameritage and the Kamoa and it all depends on what you want. If you want a sturdy, hearty case with lots of storage, you can't go wrong with an Ameritage -- and if I ever had to ship my ukulele I would do so only in that case. If, on the other hand, you want a lightweight, good looking, fashionable case, I love the Kamoa. That is going to be my go-to case to use on a daily basis, and also when traveling. For me, it is the best option due to its light weight, comfortable handle and backpack option -- it is like carrying a gig bag but with a lot more protection and style. As I mentioned above, I hope to get a red one for my Kanilea (or whenever my Kamaka feels like wearing red).
I hope this helps people that might be in the market for a high end case -- unless you can get a Calton, I think you can't go wrong with the Kamoa or the Ameritage, it just depends on whether you like a sexy, flashy option (Kamoa) or whether you prefer sturdiness and protection (Ameritage) as to which is the case for you.
